The reelmembers may conlike appearance to said member. Due to this veniently,but need not necessarily, be formed of construction, bar members A ofconcentric memg5 molded synthetic resin. According to the invenher i arein etlect reinforced substantially tion, at least one of the reelmembers is reinforced throughout their entire length, providing anexthroughout substantially its entire length by intremely rigidconstruction.

Gther features 01 the present invention rigidly mounted on asleeve 9 keyed to the drive concern, among other things, the manner inhaft 3. which the thread or the like is led onto the reel.

In the reel reel likewise embodyingthe features of the inof Figure 4, concentric member! is held in placevention. Figure 5 shows, in sectional elevation, against a shoulder onthe drive shaft by a cap still another reel embodying-the invention, thenut l3 threaded on drive shaft 3, in which case 55 In the reel of Figurel, concentric member I is held against a shoulder on the drive shaft bypreferably should be flexible. A fie:

the nut i3 is contained within the body portion 5 of said member.

Eccentric reel member 2, the construction of which is illustrated tobetter advantage in Figures 7 and 8, is shown as formed 01' a pluralityof independent bar members 5 rigidly mounted at one end thereof in thehead i5, being clamped between inner and outer ring-like members 16 andI! which together form head |5- Ring-like mem- 'ber i8 may be providedwith suitably formed peripheral slots is to receive the bar members 5.Outer ring-like member i'l' and inner ring-like member l6 may berespectively internally and externally tapered, being preferably heldtogether by screws l9, while bar members 5 may be formed with shoulders20 to aid in holding the bar members in position.

In Figure 7, the inner ring-like member I with some of the bar members 5inserted therein is shown in perspective, a bar member 6 being shownimmediately above its corresponding slot l8. Bar members 5 are thereforerigidly, demountably supported from one end thereof, being thusremovable, if desired, for replacement. Head i5 may be rotatably mountedin the desired askew position on frame member 2|, thus providing thedesired askew relationship of the axes of the two reel members. A sleeve22 may be rigidly mounted in the inner ring-like member I! of the headii to provide a bearing surface for the eccentric member 2.

It is further desirable to provide means to guide the thread or the likeinto the reel. To this end, annular guide rib 23 is formed on thesupporting head i5 for the longitudinally extending bar membars 5 or theeccentric member 2 at the point at which such supporting head l5projects over the end of concentric member I. Were no such annular guiderib provided, the thread or the like might run on the receiving end ofconcentric member i and become tangled: this possibility is precluded bythe presence of annular rib 23. During the threading up operation, whenthe thread or the like is wound more or less roughly on the reel, thelikelihood of tangling of Just this kind is much greater than otherwise.Annular guide rib 23 is efiective in preventing such tangling.

To protect that portion of the reel mechanism at the junction of reelmembers i and 2 from the action of any corrosive processing medium thatmay be used and to prevent the escape of lubricant which may stainthread or the like stored on the reel or contaminate the processingmedium, suitable sealing means may be provided. Since there is relativeoscillatory movement between reel members I and 2, the sealing memberlike sealing member 24 of suitable.

may take the form shown, has bee satisfactory. In the reel shown, oneend or the sealing member is in contact with the external surface of aboss 26 formed on the supporting head ii of the eccentric reel memberand the other end of the sealing member abuts a surface 28 formed on theinterior of the concentric reel member.

The reel shown'in Figure 5, otherwise of the same general type as thereels previously described, is adapted to supply processing medium fromthe interior of the reel to the thread or the like stored on the reel.

To this end, a hollow drive shaft 30. is provided which communicatesthrough ports 27 with the interior of concentric member is. Concentricmember id, which may be similar to concentric holes 28 which aresuitably spaced, preferably in l the slots 7 between the bar members 4of concentric reel member ia, to provide the desired distribution of theprocessing medium from the interior of the reel. Concentric member la isshown as being located on drive shaft 30. by being held against theprojecting ends of a pin 28 through the shaft 30, which pin may alsoserve to drive concentric reel member in. since the ends of pin 29 mayproject into a slot 30 in the concentric reel member ia. Other parts ofthe reel, such as concentric reel member 2, may be identical with thoseof the previously described reels.

In all of these reels, rotation of the drive shaft of the reel, by somesuitable source of power.

causes the concentric reel member to rotate. Contact between bar members4 01' this concentric reel member I and bar members 5 of eccentrio reelmember causes the latter reel member to rotate at the same angularspeed. During such rotation, which causes the thread or the like to windon the reel, the offset relationship of axes of the reel members causesthe thread or the like on the reel to transfer from one reel member tothe other, while the askew relationship of the generally cylindricalmembers causes the thread or the like to advance axially along the reelin a plurality of turns. The thread or the like is thus continuouslytemporarily stored in a plurality of spaced helical turns which arecaused to advance axially of the reel in the manner more fully explainedin application Serial No. 652,089.

Reels embodying the present invention may be made of various materials,such materials oi course being dependent in part on the use to which thereels are put. it", as an example, the reels are used in the processingof artificial silk thread, it is desirable to make the reels ofmaterials not affected by the processing medium used. For instance,depending on the use, the reels may be made oi suitable metals, rubber,resins such as phenol-aldehyde condensation products and like materials,or of metals coated with such materials, etc.

If desired, the reel parts may be molded of suitable material; forinstance, the concentric reel member shown in Figure 6 may be of anintegral molded construction, in which case a high degree of rigidity isobtained. The various parts of eccentric reel member 2, such as the barmembers 5 and the inner and outer ring-like members it and il, maylikewise be molded. Such molding, which, of course, is equivalent tocasting, such as die-casting, in the case of reels made of metal,results in numerous advantages: for instance, reel parts so formedrequire little finishing since they may be molded with a high degree ofaccuracy and smoothness, with great uniformity in size and shape of thereel parts, and at relatively low cost.

It will be noted from the drawings that, by sim ply removing thecap-screw H or nut 53, as the case may be, which holds the concentricmen her i on drive shaft a, either or both concentric member i andeccentric member 2 may be readily slipped off the support therefor andthus removed when it is desired to dismount and/or disassemble the reelas for inspection, cleaning, repair, etc. It is obvious that the reel hejust as easily reassembled and remounted. Other advantages of theinvention will be apparent to those skilled in the art.

While the reels 01' this invention have been described for use inhandling artificial silk thread, it is obvious that their use is notrestricted thereto, since they may store and advance filaments, tapes,bands, tubes, ropes, and, in fact, any article of any material capableof being so stored and advanced. As used in the specification and claimshereof, the terms mold" and molded" are to be understood, unless thecontext otherwise requires, to comprehend casting operations. It isobvious that these and numerous other changes of the nature ofmodifications may be made in the features 01 the invention to which isdirected the instant specification without thereby departin in any wayfrom the spirit oi. the invention.
